Can the electric heating pad be placed on the pneumatic chair lift Will it cause a flash of light

Reasons why the office chair lift will **:

1. The pneumatic rod of the chair mainly relies on high-pressure nitrogen to rise, and the purity of the general gas is less than 90%, which may have potential safety hazards.

2. Poor sealing will also lead to **.

3. The firmness of the material of the container wall of the air pressure rod will directly affect the safety of the chair.

The working principle of the chairlift: the lifting of the chairlift is mainly realized by the lifting device at the lower part of the chair surface, and the current lifting device is mainly divided into three categories: oil pressure, mechanical type and air pressure.

The pneumatic chair lift is the most common chairlift, there is an air pressure bar in the pneumatic chair lift, the air pressure rod is a kind of elastic element that uses gas and liquid as the working medium, can play the functions of support, buffering, braking, height adjustment and angle adjustment, etc., its basic principle is that the inside is filled with high-pressure nitrogen, because there is a through hole inside the piston, the gas pressure at both ends of the piston is equal, and the cross-sectional area of both sides of the piston is different, one end is connected with a piston rod and the other end is not, under the action of gas pressure, Generate pressure to the side with a small cross-sectional area, that is, the elastic force of the air pressure bar, and the person sits on it to give pressure to the lifting shaft, and the lifting shaft descends gently, and the speed is uniform, which can be reduced to the lowest point.

No external force is given to the lifting shaft, and the lifting shaft rises back to the highest point. Regular manufacturers use nitrogen filling, the concentration is generally more than 99%, and the pressure is about one or two atmospheres.

If you can't lift it, it may be a problem with the air bar, or you didn't remove a plastic cover at the top of the air bar when you installed it, so the air bar can't be lifted.

See if the air pressure bar is broken, the plastic on the top of the place you press to see if there is no response, if it is broken, don't sit on people, it's very dangerous.

It should be that the steam rod is not installed, re-check the steam rod to see if it is not installed or there is a problem with the steam rod itself.

The problem with the air bar, or the plastic cover on the top of the air bar when you installed it, did not remove it.

The cylinder or the seal inside is broken. In this way, the air rod cannot be raised or lowered.

When you install it, there is a plastic cover on the top of the air rod that you don't remove.

If you can't lift it, it may be a problem with the air bar, or the air bag or the sealing ring inside is broken.

I think it should be a broken lifting rod and a new one.

The plastic on the top is where you press it to see if it doesn't respond.

Yes. The lifting of the chair lift is mainly realized by the lifting device of the lower part of the chair surface, and the current lifting device is mainly divided into three categories: oil pressure, mechanical type and air pressure.

Pneumatic chair lifts are the most common type of chairlifts. There is an air pressure rod in the pneumatic chair lift, the air pressure rod is a kind of elastic element that uses gas and liquid as the working medium, can play the functions of support, buffering, braking, height adjustment and angle adjustment, its basic principle is that the inside is filled with high-pressure nitrogen, because there is a through hole in the piston, the gas pressure at both ends of the piston is equal, and the cross-sectional area of both sides of the piston is different, one end is connected with the piston rod and the other end is not, under the action of gas pressure, the pressure to the side with a small cross-sectional area is generated, that is, the elastic force of the air pressure rod, The person sits on it and puts pressure on the lifting shaft, and the lifting shaft descends gently, at a uniform speed, and can be lowered to the lowest point. If the lifting shaft is not given external force, the lifting shaft will return to the highest point.

Regular manufacturers use nitrogen to fill the air pressure bar, the concentration is generally more than 99%, and the pressure is about one or two atmospheres.

In the case of high temperature in summer or frequent lifting of seats, the pressure in the air pressure rod rises sharply, which is more likely to cause **.

If the quality of the piston is not up to par, the air will be compressed after the chair is raised to the highest level, and the piston will burst if it can't withstand the pressure, which is limited to defective products, and the German chair lift imported by my dad and their hotel has been almost 30 years old, and even the broken ones are very few.

It's true, but if the manufacturer passes the safety and quality standards, it should be fine.

It's been some years since I bought a computer chair, and a few years ago I heard that I wanted to **, but I didn't sit on it. Recently, I have heard that regular products are safe. Plus it's not hot anymore. After all, it was not as comfortable as it was after changing a few chairs. So I hope to use it.

I want to let my breath out, after all, it's too short and uncomfortable.

I checked it today and found that there was a board under the chair cushion, I don't know if it was wood, laminated or plastic. But when you uncover a little bit and see that there is a wood grain, I don't know if it is a real wood grain or a fake wood grain on the plastic? If it's a real wood grain, I don't know if it's a laminate?

In addition, some people say that there is a GS certification stamp on the air pressure rod. I checked it and it's not very clear.

Xiong Li - I still don't know, I don't know if it's a brand?

do not open i – do not heat.

do not heat up – do not open.

I hope that someone in the know can tell if this computer chair is **? Is it safe?

Thank you! At the same time, there is a reference for the landlord.

It's true, but it's generally safe.

1. The pneumatic rod of the chair mainly relies on high-pressure nitrogen to rise, and the purity of the general gas is less than 90%, which may have potential safety hazards.

2. Poor sealing will also lead to **.

3. The firmness of the material of the container wall of the air pressure rod will directly affect the safety of the chair.

So how to use it safely?

1. Choose products from regular manufacturers. Buy products with a conformity mark, don't be greedy for cheap cheap goods.

2. When buying a rotating chair, first look at whether the plastic bottom plate of the rotating chair is strong, and then slide the rotating chair back and forth.

3. When the chair is in use, do not rotate and lift it repeatedly. After using it for a period of time, it should be inspected in time, and once cracks and signs of loosening are found, it should be repaired and replaced in time.

4. Sit with a weight of more than 100 kg. To sum up, under the premise that the quality of the pneumatic chair is determined, the density of the gas is the smallest when the pressure is increased, and the possibility of leakage is relatively low, so it is relatively safe.

Don't go up or down too often, it's fine.

The same ** was reported in the evening newspapers of our region.

For the landlord asked"Increase safety or decrease security"The problem, I think:

1. Choose wooden desks and chairs;

2. If you have to enjoy the air pressure chair, please place an 8mm thick steel plate in the cushion, which is safe

Because there is the same air pressure, the risk factor is the same.

Judging whether it will ** must understand his principle, the principle of this chair is because it is filled with nitrogen, and it is lifted by air pressure by using heat.

In this confined space, the entire chair lifting is determined by air pressure, the cost of the cylinder is about 1 3 of this computer chair is filled with nitrogen, nitrogen refining is very expensive, maybe the chair itself is not expensive, but this nitrogen is very expensive.

So the most important point is that you don't want to be cheap, go for a very ordinary and cheap pneumatic chair lift. After all, the cost of all things is here, whether it is buying something in **, you get what you pay for, this truth is absolutely eternal, I remember once buying a stand-alone machine, the merchant told me that the gas tank itself is worthless, the value is the liquid inside, although they are in a large number of ** gas tanks, but this is also for environmental protection, not to save costs or how.

And the fundamental reason why this chair will happen is because it is not airtight enough, and it is filled with oxygen. When the oxygen and nitrogen are constantly rising and falling, it will rub and generate heat, which will cause it to ** in this high temperature situation, which is the reason for the chair**.

So if you want to judge whether this meaning will be **, you first have to see if it is a regular brand, produced by regular manufacturers, 90% of them may not have such a problem, and then the next step is to check whether the entire steel pipe and cylinder are broken, whether there is air leakage at the joint, or whether he is loose.

In the case of the above situations. It will be **, but if you want to achieve the first effect, it also requires a lot of conditions to be concentrated together, first of all, you have to enter oxygen, in one is to rub heat, and this heat must reach a certain standard to be possible, and once a leak occurs, the hidden device, this very light gas will quickly disappear in the air.

So don't be alarmed, such a situation is actually not very much, if it happens, it can only be said that you did it yourself, because in a situation that is not very complete, repeated lifting and lowering causes a lot of friction to generate a lot of heat, so in the process of your normal use, there should be no such ** situation.

1. The safest thing is to change to a traditional, safe and risk-free chair.

2. Do not disassemble the lift chair at will, especially the gas spring parts, if you need to repair it, please find a professional. Some people believe that it is dangerous to have gas inside the chairlift, so they disassemble it and release the gas themselves. Users are warned that the tutorials on the Internet that appear on the Internet to disassemble the lift chair by themselves for deflation should not be followed by consumers to avoid danger.

3. Raise the lift chair to the highest height with the least pressure.

There are all kinds of computer chairs on the market: there are ergonomic chairs, computer sofas, gaming chairs, and the most common computer chairs.

Reason for recommendation: What furniture do we use the most every day, aside from beds? It must be a computer chair, if a chair is not ergonomic, but only has the function of sitting, then you will inevitably have various parts of the body after sitting every day.

The above chairs are not in line with ergonomics, except for the gaming chair Handan, which imitates a little ergonomic chair like a toddler.

But in the final analysis, the gaming chair is just a brighter appearance and more eye-catching, and simply putting a small pillow can not replace the function of the lumbar pillow.

So how do you choose a good ergonomic chair? Taking the computer chair of the Yichao brand as an example, it can be summarized as follows:

A good computer chair should be composed of five parts: five-star feet, air pressure bars, chassis, cushion and backrest. Only when each member performs their duties and coordinates can they form a comfortable and durable chair.

The first part is the five-star feet, that is, the five wheels of the sliding computer chair, which bear the weight of the human body and are related to the durability of the chair. The wheels of many cheap computer chairs are made of plastic or even waste plastic, the physical properties of plastic are not good, too soft in summer and too brittle in winter, and people often encounter the situation that the wheels suddenly break when they are in use. The better wheels are made of PU and nylon composites to increase their wear resistance.

The second part is the air pressure bar, which is responsible for the lifting of the computer chair. Industry insiders pointed out that the difference between a good air pressure bar and a poor quality air pressure bar ** is about 7 times. The poor quality air pressure bar steel wall is very thin, and the valve is not tightly sealed, which will leak after a long time, resulting in the chair being unable to lift and fall.

At present, most of the office furniture produced in China cannot pass the BIFMA test. The office chair is an assembly product, and the choice can be ignored in other aspects, and the air pressure rod must be selected from a big brand. The brand of the air pressure rod will generally be on the pipe wall.

The third part is the cushion, which must conform to the curves of the human hips and thighs. The density and thickness of the sponge covered on the seat are related to the comfort of the seat, if the sponge on it is too thin and the density is not enough, it will be "unsafe" for 3 months.

The fourth part is the back of the chair, which must conform to the human body function, the tighter the fit with the curve of the human spine, the better, and the elasticity and toughness of the back of the chair are important factors in determining whether it is comfortable or not.

The fifth part is the chassis, which is the brain of the chair, through which almost all functions are realized. The chassis can manipulate the angle at which the chair reclines or leans forward, as well as the amount of recline elasticity, and the chassis function determines whether the entire seat can be reclined or only the backrest.

It's better not to. The temperature needs to be low. I'm a manufacturer of electric heating products.
